Unless there has been a quantum change in battery thinking at DJI with the Mavic 3, it does not matter if you use a third party charger capable of delivering a faster charge, because DJI have always had the Battery Management System built into the actual batteries. The 'charger' is not in fact a charger at all, but simply a power supply. You can connect a power supply capable of greater than 88 Watt capacity but it will not make the battery charge any faster.
Your statement shows a complete lack of understanding about PPS protocol, and it could't be any further away from the truth.
First of all, DJI designed the Mavic 3 battery to support PPS fast charging up to 88W. This is a fact not speculation. Their product manager has stated that with a PPS-compatible charger (88W+), the charging time for Mavic 3 battery can be reduced from 96 minutes to 78 minutes.
Now let's see how PPS works.
PPS is the most sophisticated charging protocol up to date. It is a two-way handshake protocol, both the charger and the device being charged need to have logic built-in to support PPS, otherwise they won't be able to talk to each other, and the fast charging would not work.
PPS enables the charger and the device being charged to communicate in real-time, so the charger can dynamically adjust the voltage and current, to maximize charging speed AND safety at the same time. The dynamic adjustment depends on a multitude of factors (e.g, remaining battery percentage, cable resistance, connect chip, environment temperature etc). For example, when your battery's charging status is less than 10%, it has more tendency to accept current, so the charger outputs higher current to fast charge the battery. As the battery gets full or hot, the current goes down to focus more on the safety. It all happens dynamically in the background.
